Absolute Variation in Mean Disease Activity Score (DAS) 28 Compared With Baseline at Month 6, 12, 18, and 24
DAS28 score was evaluated in participants with RA and PA. DAS28 is calculated from the number of swollen joints (SJC) and painful joints (PJC) using the 28 joints count, the erythrocyte sedimentation rate (ESR) (in millimeters per hour \[mm/hour\]) and participant's global assessment (PtGA) of disease activity (participant rated arthritis activity assessment with scores ranging 0 to 10; higher scores indicated high disease activity). DAS28 was calculated as 0.56 sqrt (DAS 28 tender joint count) + 0.28 sqrt (DAS 28 swollen joint count) + 0.70 ln(ESR \[mm/first hour\] + 0.014 (PtGA \[mm\]). Total score range: 0-9.4. DAS 28 score \<=2.6 indicated "remission in disease", score between \>2.6 and \<=3.2 indicated "mildly active disease", score between \>3.2 and \<=2.6 indicated "moderately active disease", and score \>5.1 indicated "very active disease". Absolute variation = mean result of laboratory test during period in question - result of laboratory test at baseline.

Absolute Variation in Mean Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) Score Compared With Baseline at Month 6, 12, 18, and 24
BASDAI is a set of 6 questions to determine disease activity in participant with SpA. Participants answered each 6 questions on a scale of 0 (no problem) to 10 (the worst problem). The BASDAI score is calculated by computing the mean of questions 5 and 6 and adding it to the sum of questions (Q) 1-4. This score is then divided by 5. BASDAI score = (Q1 + Q2 + Q3+ Q4+ \[Q5 + Q6/2\])/5. BASDAI score ranges from 0 (best) to 10 (worst), where higher scores meant worse condition. BASDAI score \>4 indicated "SpA active", and score \<=4 indicated "SpA inactive". Absolute variation = mean result of laboratory test during period in question - result of laboratory test at baseline.

BASFI score ranged from 0 (no functional impairment) to 10 (maximal impairment), where higher scores meant worse condition. Score \>4 indicated "significant functional impairment", and score \<=4 indicated "mild functional impairment".
